To all when; it may camera:

Be it known that I, EDWARD HOUsEN,'of Buffalo, in the county of Erie andState of New York, have invented certain new and useful Improvements ina Steam-Engine Lubricator; and I do hereby declare that the or quantityof oil on other lubricating substance to the place or places to belubrii Gated.

. It consists, essentially, in the combination, with an oil-reservoir,of a pump and 'mechan: ism for operating the same, as hereinafter firstfully set forth and described, and then pointed out in the claims. p HIn the drawings, Figuregl is a front eleva tion of myimproved pummpartsbeing shown in section. Fig. 2 is ja'se ct'ional elevation of aliibdifie'd'form of one' portion of the same.

A eis;the oil-reservoir, and B the pump cylinde'r, both partsbeing-constrilcted, essentially, I in' accordance with Letters Patent ofthe United States granted to 'me on the9th day of February, 1878-thatis, the cylinder has simply a filling-aperture, 0, through which thelubricant to be ejected gains admission. D is the piston, operated by apendulum-lever, E,- connected -with any reciprocating part of an engine,&c., by means of a connecting-rod, F. "f The 'cylinder B is secured :toone end of a shitable' frame, e, the forward end. of which carries abearingyH; for the reception of a rack-bar, I, and a standard, J,serving as a means of attachment of said pendulum-lever E by a pivot, c.The frame G is, furthermore, provided with a guide block, K, serving asa rest for the rack-bar I. Thisrack-bar has on one end a double seriesof teeth, L L, standing in opposite directio1is',- and between thetwo'sets of teeth a long'projecting tooth, M.

On the upper'end of the lever E is pivoted adouble pawl, lfl'ha'vlngitsupper extremity provided with a'spear-sliaped part, 0, acting G.FELT- in conjunction with a-spring-dog, P, in such manner as to keepeither one of the prongs 'n W-ofj said double pawl Nengaged with itsrespective ratchet-teeth L L. p

- The lend of the rack-bar I is formed into a socket, Q, having aset-screw, R, by means of which the'piston D, which enters said socketQ, is held in proper 'p osition.- p i The operation of the mech anismasdescribed will now be readily understood from the-following explanation.

The pendulum-lever E being vibrated in any well-known manner causes acorresponding vibration of the double pawl N. This pawl is kept engagedwith eitherseries of teeth, L or L, by ineansof the spring-dog P. Now,

supposing it. to be engaged with L, it moves the rack-bar away from thereservoir A until the'long tooth M reaches the arm n of said ratchet.This long tooth throws the pawl over; 'lthen the arm n engages with. theratchet-section L, and thereby causes an opposite movement of theplunger .andjrack-bar 'until the.

Saidlong tooth reaches the arm n and throws the pawl back again to theposition firstdescribed. In this manner the rack-barisre ciprocatedintermittingly by the pendulumlever and its ratchet-connection, the saidrackbar moving the space of one tooth for every revolution of theengine-shaft-or other parts from which the pendulum receives its motion.

- In order to adjust the stroke of the pendulum-lever with reference tothat part of the engine from which it receives its motion, it (the vsaid pendulum-lever) is provided with a slot-hole, E, wherein the stud Fof the conthe pendulunr-E if the stroke is large, or

decrease the same when short, in a mannerreadily understood by anyskilled mechanic.

In the pump-cylinder B is the ingress aperture G, which fills the saidcylinder, as already mentioned. The piston D is adjustable within thesocket Q by the set-screw Rthat V is to say, it may be pushed fartherinto or drawn out of the socket Q when the rack-bar I is farthest awayfrom the reservoir A. The

- end of said piston has then just cleared the said aperture 0. When insuch a position the pump will eject to its full capacity with everystroke of the piston, because the entirecylinder will be filled withsaid lubricant and forced out of the same as soon as the piston haspassed the supply-opening.

But supposing the piston is pushed into the socket Q the spaceOfone-half inch beyond its first-described position; in this case thepiston D in' moving out of the cylinder B will pass beyond the aperture0 in the direction toward the pendulum -lever one-halfan inch, and theaperture being, say, onequarter of an inch in diameter, this leavesthree-fourths of an inch of piston-stroke available for ejecting thelubricant.

It will now be further observed that by pushing the piston D so far intothe socket Q as to compel the piston to make its full stroke of one andone-half inch on that side of the cylinder toward the pendulum-lever F,measuring from the ingress aperture 0, no lubricant would be ejectedfrom the cylinder to the part to be lubricated, because all thelubricant entering the cylinder would .be returned to the reservoirthrough the ingressopening 0.

It is therefore self-evident that the two eX- tremes of this pump beinga delivery of oil or the number of strokes of the piston, by simplypushing the piston l) farther into or withdrawing it out of the socket Qto the desired point.

For this purpose indicating-marks maybe made on the piston showing thenumber of gallons or other fixed quantity ejected by the pump in acertain space of time, provided the strokes were predetermined andlimited to the proper number; but, since this number of strokes isconstantly varying with different engines, such an arrangement would beimpracticable, and I prefer that a few trials should be made in everycase until the desired limit of capacity of the pump has been fixed byexperiment.

It is now perfectlyevident thatthe mechanism' described for varying thequantity of discharge of my pumpis applicable to many other pumps forforcing liquids, while the mechanical movement for converting thependulum motion described into'an intermittent rectilinear reciprocatingmotion is' likewise applicable to many mechanical devices where anintermittent reciprocating motion is a desidera tum. I haveheretoforedescribed the piston as being rendered adjustable with respect of theingress-opening in the cylinder, whereby the quantity of the dischargemay be adjusted as specified. This arrangement may be modified, however,and the piston made non-adjustable, but the cylinder made adjustable,reversin g the order of things described. In Fig. 2 I have shown such anarrangement. Here the piston D has a fixed unalterable stroke withinpredetermined limits of space, but the cylinder 0 is rendered adjustableby moving it nearer to or farther away from the piston,

which device. would act in precisely the same manner as that alreadydescribed, and be, therefore, a mechanical equivalent thereof.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent 1. A lubricator or other pump having a pistonwithin a pump-cylinder, said piston being adjustably arranged withrespect of the ingress-openin g in. said pump-cylinder, whereby thequantity of discharge may be adjusted, substantially asand for theobject specified.

2. Anoil-pump lubricator having a reciprocating plunger with 'a fixedstroke operating within a cylinder having an ingress and a dischargeopening, said plunger and ingress-opening being arranged in relation toeach other with the capability of adjusting the distance which thepiston travels beyond the ingressopening, whereby the quantity ofdischarge is rendered adjustable, substantially as and for the purposespecified.

3. A pump having an ingress-opening to and a discharge-opening from itscylinder, in combination with a plunger capable of being renderedadjustable with respect of the distance which it travels beyond theingressopening of said cylinder, whereby the quantity of discharge isrendered variable, substantially as and for the object stated.

4. The combination, with the oil-reservoir A, 7

having the cylinder B, provided with an ingress-opening, C, of theplunger D and the mechanism for operating said plunger, the cylinderorplunger being adjustable with respect ofthe said ingress-opening tothe cylinder, whereby the quantity of discharge is rendered adjustable,substantially as and for the purpose stated.

5. In a lubricating-pump, the combination, with the holding-bar I,reciprocating within fixed and unalterable limits, of the piston D,adjustably fixed within said holding bar for the purpose of altering thequantity of discharge of said pump, as and for the object specified.

6. In lubricating-pumps, the device described for imparting areoiprocatin g motion to the piston, consisting, essentially, of thelever E, double ratchet-pawl N, and ratchet-bar 1, provided with twosets of oppositely -'pointing teeth and a long tooth between the twosets, as and for the use and purpose stated.

7. In lubricating-pumps, the combination, with the bed-plate G, havingthe bearing H and rest K, of the rack-bar I, provided with the doubleseries of ratchet-teeth L L and a central tooth, M, the pendulum-leverE, and

the double ratchet-pawl N, pivoted to the pendulum-lever, as and for thepurpose indicated.

8; In lubricating-pumps, the combination, with the pendulum-lever E,having the double pawl N, provided with the spear-shaped part 0, of thespring-dog P, as and for the object stated.

In testimony that I claim the foregoing as my invention I have heretoset my hand and affixed my seal in the presence of two subscribingwitnesses. I
